'To all whom it may concern/. I

Be it known that I, FlannnaroK RJFRENCH,

a citizen of the United States,'residing in the. city and county of SanFrancisco, State of 1 California, have invented an 'll'nprovement inConveying Apparatus; and'I hereby declare the following to be a full,clear, and exact description of the same.

My invention relates to an apparatus designed for transporting burdensin bothhori zontal and vertical directions;

It consists of parallel'suspended cables inclosing any area and adaptedto operate between four supports, a transverse burdencarrier movablebetween said supports,'and

means for also moving the burden-carrier transversely between the cablesand at any point between the supports, whereby thebur-I den can betransferred toanyp'oint within the area and raised or lowered withoutanindependent mainfall-line? v My invention also comprises details ofconstruction, which will be'more fully explained by reference to theaccompanying'drawings, in whichj e Figure 1 is a general perspectiveview of the apparatus. Fig. 2 is a view of the sheaves which areattached to the top of the towers. j Fig. 3 shows'the arrangement of thetrolleys tion, depending upon the contour of theground or thepositionwhere the apparatus is to be operated. Spars or timbers with, suitableguys or supports may serve, or builttowers or where the contour of theground is suitable the elevation'of the ground may serve, for thesupport of'the cable-carrying sheaves. The sheaves upon" the towers A Bare constructed as shownin Fig. 2, in'whioh three different pulleys 2,3, and 4 are-turna'bleupon pins in a single frame or frames, as at 5,and these frames or blocks are suitably connected with the towers orsupports by links, as are, or other suitable connections,

which will allow the parts'to yield to the changing positions or strainsupon which pass around them.

the cables 7 and 8 are two drums, connected so as to and 9 and 10 10 thefirst two passingaround the drum 7 and the second pair aroun'ditheAround these drums passcables 9 6o drulnl8. The cables 9 and 9 and 1010. may

As sho'wnin the drawings, vthe cables 9 and thence beneathguiding-pulleys 11 upontrol- 'ley-carriers 12', thence around pulleys13, at-

Bythisarrangement it :1 33 will be 'seen that whenever'thedru'ins'are re 15,upon the sides opposite to'the attachments volved in unison ineither'direction-Ithe trol-f .1ey-carriers12 will besilnllltaneouslymoved outward awaylfrom the towersA and 13 or ofrevolution of the drums;

able form or construction I *Iha've here shown I them as triangularframesjin: one angle of "whichthe pulleys or sheaves 11 are journaled,

and in theother two'anglesare journ'aledthe sheaves 16. and 17. '.-18'-and' 19 are two drums re'volu'bleinunt "son and around whichare woundthe ropes 20 and 21in such a manner that one of said ropes wil pay outor be lengtheneiwh il it I a other will be correspondingly drawn'in'orshortened. The rope 20 passes outwardly around the sheave'3 of the*towerIA', "thence around the sheave 16 of the tr01ley-'carrier,'

thence around a sheave 2,2, which is journaled in a frame or blockconnected with the burden-support, thence around the sheave 17 of ,65 ifp the object in either casebeingfthat'one cable e p of each pair shouldpay out while theother c The operation of the device will then be asfollows: The two drums 7 and 8,1'evolving together, if they are turnedso that their top sides move to the left the cables will be coiled anduncoiled upon the drums in unison, so that the trolleys will move inunison toward the engine. If the drums are reversed, the cables willcause the trolleys to move in the opposite direction or away from theengine. While this motion is taking place, the burden will remain at thesame relative position between the trolleys 12,having first been liftedfrom the surface by the operation of the drums 18 and 19 and the cables20 and 21. Thus a burden having been lifted from a point near the towerA may be transported by the movements of the drums 7 and S and thecables 9 and 10 to a point near to the tower G, and then by theoperation of the drums 18 and 19 and the cables 20 and 21 it may betransferred transversely to a point near the tower D, after which bystopping one of the drums 18 or 19 and allowing the cable to uncoil fromthe other the load may be lowered by the lengthening of thesupporting-cable and deposited at any desired point. In this manner theload or burden may be picked up at any point within the area between thetowers or supports A B C D and transferred to any other point withinsaid area and there deposited.

If it is desired to make aerial dumps, as in discharging loads of earthor rock, it may be elfected by any well known or suitable deviceemployed for such purposes.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination in a conveying apparatus of parallel pairs ofsuspending-cables, supports over which said cables pass, winding-drumsaround which the cables are movable, trolleys suspended and movable uponthe cables, other cables passing around sheaves in said trolleys and aburden-carrier suspended by said cables between the parallel cables, andmeans by which said burdencarrier may be moved transversely between theparallel cables.

2. The combination in a conveying apparatus of pairs of parallel cables,supports over which said cables pass, trolleys suspended and movableupon the cablesanechanism by which said cables are moved to cause thetrolleys to travel outwardly or inwardly in unison, a burden carrier,supplemental cables from which the carrier is suspended between theparallel cables, and means for actuating the supplemental cables to movethe carrier transversely between the parallel cables.

The combination in a conveying apparatus of two sets of parallel inhauland outhaul cables, trolleys with which said cables are connected fromopposite sides whereby said trolleys are movable in unison, aburdencarrier and supplemental cables by which it is suspended betweenthe parallel cables, guidesheaves upon the trolleys and upon the fixedsupports, and winding-drums by which the supplemental cables areactuated to move the burden transversely, or to raise or lower it.

4. The combination in a conveying apparatus of two pairs of parallelinhaul and outhaul cables,with direction-pulleys overwhich they pass,trolleys movable one upon each of said parallel cables, and withopposite sides of which the ends of the cables are connected whereby thetrolleys are moved in unison, and a burden-carrier and supplementalcables by which it is suspended between the trolleycarriers, and meansby which the cables are actuated to raise or lower the burden or to moveit transversely between the parallel cables.

5. The combination with pairs of parallel cables and their actuatingmechanism, and trolleys suspended and movable upon the ca bles, ofsupplemental cables connected to the trolleys, a burden-carrierconnected to the latter cables, and means for actuating the supplementalcables to cause the burden-carrier to be moved transversely between theparallel cables.

6. The combination in a conveying apparatus of two sets of parallelinhaul and outhaul cables, trolleys with which said cables are connectedfrom opposite sides, windingdrums by which the cables are driven and thetrolleys moved in unison in either direction, supplemental winding-drumsand supplemental. cables connected and movable thereby, guide-sheavesupon the towers and the trolleys, and a burden-carrier connected to thesupplemental cables and located between the main cables, and capable ofbeing moved transversely thereby between the parallel cables.
